Well all this talk of drifting and I sort of did one today by accident. Was wet I looked down and was doing 30-40mph nice gap in front (as far as I can remember) one car in front and clear road ahead of her. She braked so I did too but then decided to stop completely, at this point I was still braking but realised I wasn't going to stop so added more pressure front and rear which resulted in what felt like both ends locking up?? Front slid one way and rear the other and back again. I put my left foot down to stop me from dropping it, after I stopped I tried to horn but as usual I found the indicator again Laughing I guess this whole thing is partly my fault

Second was completely my fault when I saw a guy about to step on the crossing and put too much on the rear. I was going quite slow so it wasn't too bad, was pretty cool actually Laughing

Well you learn from your mistakes and now I know what it feels like to lock up the wheels!

The moment you lock up, rlease the brake then re apply it. Its saved my ass several times.

To be honest I can't remember what I did to get it straight again Laughing

Would it have helped if the damper was on?

Firstly, I think this is worthy of a 'Cool Story Bro' pic. Unfortunatly I'm too lazy to find one, but I hope someone brings one along soon, they rock.

Secondly, I agree with the can't remember. I think it's actually why helmets are mandatory under UK Law, its because when something like this happens we pull a stupid face, the helmet keeps us looking cool Cool

From the slow speed rear locks i've had, all have been fairly straight line jobs and equalled out without really knowing what i've done. I dont think the damper helps too much as I cant say i'd noticed a difference between my 03 or 07 RRs - the 07 has a damper, the 03 didnt.

The biggest thing i've noticed is square or low tread (in wet) normally makes it a damn site easier to lock up the back, especially with any moderate front braking.

Most out of shape one i've had was on my 125 but that was a cruiser layout, the entire back done about 35 deg and came to a stop, that was quite interesting...

Looks like you locked it or skidded.

Do you normally ride very slow?

Why are you using the back brake for emergency stops?

Steering damper?

To stop lockups?


Interesting......

It was wet? so brake bias moves less off the front as you dont want the front locking and going down under you?

I don't have a steering damper, is that why I lifted the bike up when I gave it some throttle?

When I locked the front at 60mph, the steering got pulled to right lock and tried with all my might I couldn't straighten it. Maybe a damper would help hold the bars straight in that situation.

Luckily I managed to stay upright, but was flung side to side because I released the brake while the steering was at full lock (it was my only choice). Trying to turn it back wasn't possible (or if it was it would have put me over).

Perhaps a steering damper would have held the front wheel more straight?

But then again, when you consider that the front wheel normally does what it wants to do to find the best grip, full lock was probably best for it.

Apprently if you lock up the front you should release slowly. I don't think I did at the time even though I knew this. It worked though.

Reading some of the opinions/theories proffered here makes me realise why so many BCFers keep chucking their bikes down the road.

I choose not to use rear braking unless i'm in town at low speeds where the front is too agressive to use.
In emergency stops the rear will nearly always lock due to the shift in weight over the front, hence why i don't use it and tend to get a better 'feel' for the front. Only the front brakes will pull you up fast.
I sometimes use the rear along with the front for longer higher speed controlled stops.
Not saying i'm using them correctly but that's how i use them. Mr. Green

Theres a particular roundabout near mine with HORRENDOUS adverse camber, made worse by lumpy tarmac where gaz mains have been dug up in the past. EVERY time I have to use that lane i drift. Fun but not pleasant. I'm not exactly unfamiliar with lockup's either, but I tend to stay calm and give it more of a "oo, cheeky" than a "FUCK I'M GONNA DIE" reaction. It's worked for me Smile Never came off. Even when my front end slid out about a foot on some ice, I managed to stay calm... Maybe i'm just stupid? not complaining Wink

So. Let me get this straight.

You've been riding for god knows how long, and you've never locked up the brakes before? And then, when you did, you didn't immediately learn from the experience?

Sounds like you need to seriously reflect on any aspects of your riding which you feel are poor, and try to improve them.

I used the rear because it was wet! I thought that's what you're supposed to do Laughing

Tyres are front: Pirelli Diablo something and rear is Maxxis something. TBH the rear looks a bit rubbish for wet riding.

There were no skips or hops just a smooth slide, the first was all over the place because the front locked as well and went its own way. The second must have looked pretty cool Laughing

With the first I got caught out because I didn't expect her to stop as the road was clear and the only way she could go was straight as there are no side roads until further up

Nope not locked up before. Yes I have learnt from it. Keep more distance, expect the unexpected and if I do lock up release then re-apply

EDIT: Also I didn't mean the steering damper to stop lock ups I meant to help steering wise when the front locks and goes its own way

Be fair on him. I think he is young and likes to post on forums, thus why he made loads of threads on what do you think of this bike before purchasing the B1H. When you aren't 100% sure on thigs, you will post on here and ask questions.

The other issur is that he doesn't like to ride extremely fast which he said himself. Not sure what the monster is like but anyway surprisng that he hasn't lock up before, but again, he has said he likes to take it easy.

I feel his lack is rev/ speed was also confirmed with the fact that he said the B1H was quiet. It is in low revs but hit 8, and especially 12k it isn't at all.

Maybe the name racer is misleading or what not, but he is young.

Laughing That's me right there Thumbs Up I'm starting to ride in higher revs now though, maybe I was too used to the twin Wink

I usually get my braking right but it was pretty wet and I've only ridden in the rain a handful of times, only twice on the B1 in fact. Rear tyre needs to go at some point too, not excuses but additional factors!

I locked the front up at 80 down to 40 when i first got this bike, it was pretty un-dramatic really, bloke behind me couldn't see through the plume of smoke though.

He said i should have been off, guess i got lucky.
